Urban green spaces activities: A preparatory groundwork for a safety management system

Urban green spaces works and maintenance are high-risk activities and usually represent possible sources of injuries. The management issues are complex and strongly influenced by companies’ policies in terms of safety management and human factor. A high number of tasks –including protecting public health and safety and safe working procedures- need to be faced by professional arborists or gardeners. The present paper provides a preparatory groundwork for modelling and describing the real risk levels during the above mentioned activities. The methodology represents a useful tool for decision making both for group leaders and safety coordinators. This goal is reached by collecting data emerging from several workplaces located in North East Italy and regarding injuries frequency and severity. The preliminary results point out that the most frequent injuries in green maintenance activities are represented by cuts, contusions, and ocular lesions, but none of them leads to particularly serious consequences for the operators; indeed the high levels of severity are related to traumas, fractures, and acute lumbar herniated disc. The riskiest activities are related to pruning, especially using mobile elevating work platforms, and grass cutting, especially when operated in escarpments and banks. Workers’ behaviour and companies’ safety policies are key elements for a correct safety management system.
